beneficially own financial

"Armistice Capital exercises voting and investment power and thus may be deemed to beneficially own"

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

shared voting power financial

"Shared Voting Power 142,728.00 7 | Sole Dispositive Power 0.00 8 | Shared Dispositive Power"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

shared dispositive power financial

"Shared Voting Power 142,728.00 7 | Sole Dispositive Power 0.00 8 | Shared Dispositive Power"

Investment Management Agreement financial

"pursuant to an Investment Management Agreement, Armistice Capital exercises voting and investment power"

An investment management agreement is a written contract that hires a professional to make buying, selling and strategy decisions for an investment account or fund, and sets out their duties, fees, risk limits, performance measures and reporting requirements. It matters to investors because the agreement determines who controls the money, how much the service costs, what risks are allowed, and how success or failure is measured—think of it as the service contract that defines expectations and remedies for a hired portfolio manager.

exempted company financial

"The Master Fund, a Cayman Islands exempted company that is an investment advisory client"
